BONDING AND TIE PLATE FOR BUILDING-BLOCKS.

Specification of Letters Patent.

Patented Dec. 6, 1910.

To all whom it may concern:

Be it known that we, GEORGE M. GRIsworn) and HUGH C. BEAGLEY, citizens of the United States, residing at Kingman, in the county of Kingman and State of Kansas, have invented certain new and useful Improvements in Bonding and Tie Plates for Building-Blocks, of which the following is a specification.

Our invention relates to ties for holding building blocks in alinement with each other and binding the building blocks together, and particularly to a tie designed not'only to hold the building blocks in abutting relation to each other, but in alinement with each other, the object being to provide a tie or reinforcement of this character which is particularly suit-able to buildings wherein there is an outward or inward thrust against the wall such as in silos, tanks, or like structures.

For a full understanding of the invention reference is to be had to the following description and accompanying drawings, in which Figure 1 is a perspective view of our improved tie-plate in place in a wall. Fig. 2 is a plan view thereof, and Fig. 3 is a detail perspective view showing the blank from which the tie-plate is formed.

Corresponding and like parts are referred to in the following description and indicated in all the views of the accompanying drawing by the same reference characters.

Referring to these figures 2 designates the building blocks which may be made of any suitable material, these blocks being hollow and preferably formed with a transverse median wall 3, the ends of the blocks being formed with the transverse end walls 4. In the figure we show these blocks as forming part of a partition wall, or like vertical structure, for which our improved tie and reinforcement is particularly suitable.

The improved tie is shown in Fig. 1. It comprises the rectangular somewhat elon gated body portion 5 with the two oppositely disposed laterally projecting wings 6 and the end-wing 7 The blank for this tie is shown in Fig. '3. The lines on which these wings 6 and 7 are to be bent are indicated by dotted lines. The middle of the body portion is preferably cut away as at 8 to form an opening extending longitudinally of the body. The outer end of the tie-plate is also formed with an opening 9 which ez itends transversely of the longitudinal axls of the body, These openings are for the purpose of bonding the tie-plate to the blocks or bricks of the wall.

It will of course, be understood, that while we have shown the building blocks 2 as being made solid, the wall might be built up of bricks or sections, and have the general form illustrated.

The operation of our invention will be obvious from the drawing. The tie-plate is placed upon the upper ends of the adjoining building blocks and the side wings 6 are turned down so as to engage with the inside faces of the adjacent end-walls of the blocks, while the end wing 7 is turned down to engage with the faces of the building blocks, either on the inside or outside of the wall. The two openings in the building block act to set or bind the metal-plate in place after the mortar has been spread over the ends of the blocks, thus the mortar joins and connects the building blocks, and after the mortar fills the openings in the tie-plate it helps hold the metal tie plate in place so that the tie-plate and blocks are held in rigid relation with each other.

The wings 6 have a length equal to the width of the hollow interior of the block and thus contact with the walls of the block, and thus the tie-plate is held rigidly in posi tion and cannot shift transversely to the building blocks. It. is firmly held in position by reason of the downwardly bent wings 7. The side wings 6 prevent also any lateral shifting of the tie-plate and thus it will be seen that the building blocks are bonded or tied with each other by the tieplate, and prevented from any lateral or longitudinal shifting, and that the tie-plate is bonded to the mortar adjoining the blocks.

Our invention is simple, can be easily made, easily applied, and is entirely effective in practice, particularly when used with walls which are subjected to thrust.

Having thus described the invention what is claimed as new is 1. A tie-plate for building blocks, one face of the plate being smooth, the other face having lateral wings projecting at right angles to the tie-plate but of less length than the same, one end of the tie-plate beyond the wings having a transversely extending flange at right angles to the plate and projecting from the same face of the plate as the lateral wings, the other end of the tie plate terminating coincident with the adjacent ends of the lateral wings.

2. A tie-plate for building blocks having lateral wings extending at right angles to the tie-plate but of less length than the tieplate, one end of the tie-plate beyond the wings having a flange extending at right angles to the plate and projecting from the same face of the plate as the lateral wings, said tie-plate being provided with bonding openlngs.

3. In combination with a wall formed of I hollow building blocks, the end walls of said blocks abutting against each other, of a tieplate disposed upon the adjacent ends of said blocks, said tie-plate having lateral flanges bent at right angles to the plate and extending into the hollow interiors of the blocks, said tie-plate at one end extending to the face of the blocks and being provided with a flange bent at right angles to the plate and projecting from the same face of the plate as the lateral wings, said flange engaging with said block faces.

4. In a wall, the combination with adjacent building blocks, said blocks being hollow of a tie-plate engaging with the abutting ends of the blocks, said tie-plate having lateral wings bent at right angles to the plate and having a length equal to the width of the hollow interior of the block, said tieplate extending beyond the wings and being formed at its extremity with a flange bent at right angles with the plate and projecting from the same face of the plate as said lateral wings and adapted to engage the faces of adjacent blocks of the same course, the tie-plate being further provided with a longitudinally extending opening and with-a transversely extending opening, the transversely extending opening being adjacent to the bent end of the tie-plate.

In testimony whereof, we aflix our signatures in presence of two witnesses.
